The airplane sustained substantial damage to the right wing and empennage.

The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.

An automated weather observation system about 26 nautical miles from the accident site reported that, about the time of the accident, the wind was from 010° at 9 knots, gusting to 15 knots. 

The pilot reported weather conditions as good other than gusting wind when entering and in the river valley.
